Not sure which direction of square you are having a problem with. If the blade is not parallel to the miter gauge slot it might be best to take it back for a new one, as mentioned above. As long as it is, you also need to make sure that the fence is parallel to the blade (basically aligned to the miter gauge slot). The manual should explain how to adjust it. Another source of problems while ripping is trying to rip a piece of wood that does not have a straight (factory) edge on one side. Without a jig, it is difficult and often dangerous to try making a straight cut if you don’t have a straight edge edge to run against the fence. You also mention having problems with the riving knife. If the knife is not perfectly aligned with the blade, it can cause a deflection as the piece passes the knife. The knife must also not be wider than the kerf of the blade (or the blade should not be narrower than the knife). If you are using the blade that came with the saw, that should not be a problem.

If the problem is that the bade is not square to the table top, you cannot necessarily rely on the scale on the tilt mechanism. Just using a small square is usually good enough but I like using a digital angle gauge to set the blade angle. Makes for quick and accurate setups for any angle. Also, you need to make sure that the throat plate is perfectly level with the table top or it will throw it off no matter how accurately you set the blade.

If you are having trouble with cross cuts being square, again, the blade has to first be parallel to the miter gauge slot. If it is, make sure that the miter gauge does not have too much play in the slot. Many have adjustments to make sure that they are tight but not so tight that they bind. If not, you can use aluminum tape (used for AC duct work) as a shim to tighten it in the slot. I use my digital angle gauge to set the miter gauge by hanging the miter gauge on the edge of the table saw. Finally, the most important safety and accuracy tool for my table saw is a cross cut sled. Everyone should make one of these. A well made sled not only makes 90 degree cross cuts much more accurate but it allows me to make cuts safely that I would never attempt without it.
